Distributed resource management for a plurality of local media gateways to provide video conferencing

ABSTRACT

Media gateways (MGs), grouped into a hierarchy, are operable to provide a multiparty conferencing among client devices. Gateway resources such as processors, Codecs and network interfaces are aggregated at each MG to establish distributed connection sessions based on resource management metrics such as minimizing total network. The distributed connection sessions are utilized to provide the multiparty conferencing. Each MG may aggregate the gateway resources, which may be determined utilizing a look-up table, from other MGs for sharing among the MGs. Each MG may be activated to provide the media gateway controller (MGC) processing utilizing the shared aggregated gateway resources. A MG may be de-activated from the MGC processing when needed and the associated connection sessions may be subsequently released. Gateway resources are managed at each MG based on the resource management metrics in order to establish distributed connection sessions to support the multiparty conferencing among the client devices.

DETAILED DESCRIPTION OF THE INVENTION

Certain embodiments of the invention may be found in a method and system for distributed resource management for a plurality of local media gateways to provide video conferencing. In various embodiments of the invention, a plurality of media gateways (MGs) may be operable to provide multiparty conferencing among a plurality of client devices. Gateway resources such as processors, Codecs and device/network interfaces may be aggregated at each MG to establish distributed connection sessions at each MG based on resource management metrics. The multiparty conferencing may be implemented or provided by utilizing the distributed connection sessions. In an exemplary embodiment of the invention, the MGs may be grouped into a tree-like hierarchy based on the resource management metrics. The distributed connection sessions for the multiparty conferencing may be established at each MG by minimizing total network power consumption, minimizing total end-to-end latency, and/or maximizing aggregate network bandwidth, for example. Each MG may aggregate the gateway resources, which may be determined utilizing a look-up table indexed via the resource management metrics, from other MGs. The resulting gateway resources aggregated at each MG may be shared among the MGs. In an exemplary embodiment of the invention, each MG may be activated, when needed, to provide the media gateway controller (MGC) processing such as gateway resource management by sharing the aggregated gateway resources. In instances where a specific client device becomes inactive in the call, a serving MG for the specific client device may be de-activated from the MGC processing. Corresponding connection sessions between the specific client device and the serving MG may be subsequently released. Distributed gateway resource management may be performed at each MG based on the resource management metrics to establish distributed connection sessions for the multiparty conferencing.

FIG. 1 is a block diagram illustrating an exemplary architecture of a media gateway system that is operable to support distributed resource management for a plurality of local media gateways to provide video conferencing, in accordance with an embodiment of the invention. Referring to FIG. 1, there is shown a media gateway hierarchy 100 that may be utilized to support services such as video conferencing.

The media gateway hierarchy 100 comprises a plurality of media gateways (MGs) 110 a-140 h and a plurality of client devices 150 ₁-150 ₁₆. In an exemplary embodiment of the invention, the media gateway hierarchy 100 may comprise a plurality of hierarchy layers 110-140. The MGs 110 a-140 h may be logically organized or grouped themselves into the corresponding hierarchy layers 110-140 based on various path selection metrics such as resource management metrics or policies. For example, the plurality of MGs 110 a-140 h may be grouped into the hierarchy layers 110-140 by minimizing the total network power consumption, by minimizing the end-to-end total latency, and/or by maximizing the aggregate network bandwidth. A hierarchy layer such as the hierarchy layer 130 may comprise MGs such as the MGs 130 a-130 d that may be selected based on resource management metrics or policies such as power consumption, end-to-end latency and/or aggregate network bandwidth. The hierarchy layers 110-140 may be ordered hierarchically according to resource management metrics or policies, which may be selected by the service providers and/or users. For example, a higher hierarchy layer within media gateway hierarchy 100 may comprise MGs corresponding to lower power consumption, lower latency, and/or higher aggregate network bandwidth, in comparison with a lower hierarchy layer. In an exemplary embodiment of the invention, the plurality of MGs 110 a-140 h may be organized themselves into a tree-like structure within the media gateway hierarchy 100 based on resource management metrics or policies such as minimizing power consumption, minimizing latency and/or maximizing aggregate network bandwidth. The MGs in a low hierarchy layer of the media gateway hierarchy 100 may be point-to-point connected in a tree-like fashion with MGs in the next higher hierarchy layer. For example, in the hierarchy layer 140, both the MGs 140 a and 140 b may be point-to-point connected to the same MG 130 a in the hierarchy layer 130.

A MG such as the MG 140 a may comprise suitable logic, circuitry, interfaces and/or code that are operable to implement and manage connection sessions between the MG 140 a and other local MGs such as the MG 130 a. Depending on gateway processing capability, each MG such as the MG 140 a may serve one or more client devices such as the client devices 150 ₁-150 ₂ providing services such as a multiparty audio and video (AV) conferencing and messaging among the client devices 150 ₁-150 ₁₆. The MG 140 a may be operable to perform various media gateway functions such as, for example, packetization, data compression, media streaming and/or protocol processing. In this regard, the MG 140 a may be operable to interface with various client devices and/or networks for the desired services. The MG 140 a may enable voice, video, data and/or fax to be transmitted or communicated over various communication protocols such as Internet and other protocols, and interface with third party equipment so as to facilitate enhanced voice and data services. For example, the MG 140 a may be activated to manage a call originated from the client devices 150 ₁ during the multiparty AV conferencing and messaging. In this regard, the MG 140 a may be operable to process and connect different types of media streams such as, for example, audio recordings, music and videos, during the call. In an exemplary embodiment of the invention, the MG 140 a may provide or perform the media mapping and/or transcoding functions between similar and/or potentially dissimilar networks such as, for example, cable, DLS, mobile networks (2G, 2.5G and 3G radio access networks) and/or private branch exchange (PBX). For example, the MG 140 a may be configured to packetize a media stream received from circuit-switched network facilities (trunks, loops) to deliver or communicate the resulting packetized media stream to a packet network such as the Internet.

In an exemplary embodiment of the invention, the MG 140 a may operate or function as a (local) media gateway controller (MGC) providing call control and signaling functionality such as, for example, call routing, signaling, call services and the like, to support various telephony applications or features such as 3-way conferencing. The MG 140 a may be operable to communicate with other local MGs by means of protocols such as Media Gateway Control Protocol (MGCP) or H.323 or Session Initiation Protocol (SIP). The MG 140 a may be operable to set up and manage connection sessions between the MG 140 a and other local MGs. The MG 140 a may handle the registration and management of gateway resources to support associated connection sessions at the MG 140 a. A connection session between the MG 140 a and the MG 130 a, for example, comprises a sequence of client-server interactions within a timeframe over a connection or link established between the MG 140 a and the MG 130 a. A connection session may be described through an associated session profile comprising various session parameters such as, for example, type of service (ToS), session ID, addresses and ports, time of live. In an exemplary embodiment of the invention, the MG 140 a may aggregate gateway resources such as, for example, media encoders/decoders, processors, and device/network interfaces, from other local MGs. The MG 140 a may manage the aggregated gateway resources for sharing among the local MGs to support connection sessions established for the desired services. The MG 140 a may activate, maintain, update, and/or terminate the connection sessions per associated session profiles. In an exemplary embodiment of the invention, the MG 140 a may be dynamically activated or de-activated in an as needed basis for the MGC processing.

A client device such as the client device 150 ₁ may comprise suitable logic, circuitry, interfaces and/or code that are operable to receive services provided from different core networks through the MG 140 a. In various exemplary embodiments of the invention, the client device 150 ₁ may communicate or exchange information through the MG 140 a with other client devices registered to the MG 140 a and/or other MGs. In this regard, the client device 150 ₁ may be operable to share information with other local client devices such as client devices 150 ₂ as well as with remote client devices such as the client devices 150 ₇ through the MG 140 a. The client device 150 ₁ may receive services from service providers as well as networked client devices such as the client devices 150 ₇.

In an exemplary operation, the MGs 110 a-140 h may be organized into different hierarchy layers 110-140 in the media gateway hierarchy 100 to achieve routing metrics or policies such as, for example, minimizing the end-to-end total latency, and/or maximizing the aggregate network bandwidth. Each MG in the media gateway hierarchy 100 may be enabled to perform various MGC processing such as registration and resource management in an as needed basis. Each MG such as the MG 140 a may be activated to serve as a local call controller, or a call agent, to support telephony features such as multiparty conferencing. The client devices 150 ₁-150 ₂ may communicate with the serving MG 140 a over device-dependent interfaces such as cable, DSL, IP LAN, WiFi, Femtocell, LTE and WiMAX. The client devices 150 ₁-150 ₂ may communicate with one or more other MGs such as the MGs 130 a and 120 a via the serving MG 140 a. Each MG in the media gateway hierarchy 100 may be operable to establish and manage point-to-point connection sessions during the call. Communication between MGs such as the MGs 140 b and 130 a in the media gateway hierarchy 100 may be carried out over corresponding distributed connection sessions to serve the client devices 150 ₁-150 ₂ during the call.

FIG. 3 is a flow chart illustrating exemplary steps that may be performed to provide a multiparty audio and video (AV) conference call utilizing distributed connection sessions, in accordance with an embodiment of the invention. Referring to FIG. 3, the client devices 150 ₁-150 ₁₆ may register to participate in a multiparty AV conferencing. During the multiparty AV conferencing, a client device such as the client device 150 ₁ may intend to start a call to one or more destination client devices 150 ₃ and 150 ₆, for example. The exemplary steps may begin with step 302, in which one or more MGs between the originating client device 150 ₁ and a destination client device such as the client device 150 ₃ may be identified or selected to support the call based on resource management metrics or policies selected by the service providers or users. For example, the MGs 140 a, 130 a, and 140 b may be selected for the call according to one or more resource management metrics such as minimizing the end-to-end total latency. In step 304, each of the selected MGs 140 a, 130 a, and 140 b may be activated to provide the MGC processing. In step 306, at each of the selected MGs, gateway resources such as processors, Codecs and/or interfacing capabilities may be aggregated. For example, a MG such as the MG 140 a may communicate with other local MGs such as the MG 130 a for available gateway resources which may be shared among the client devices 150 ₁-150 ₁₆. Each MG may share the aggregated gateway resources and may perform resource allocation based on one or more resource management metrics. In step 308, each MG may be operable to establish or set up distributed connection sessions at each selected MG for the call. In step 310, each MG may utilize the allocated gateway resources to initiate corresponding distributed connection sessions to support the call to the client devices 150 ₃ and 150 ₆ from the client device 150 ₁.

FIG. 4 is a flow chart illustrating exemplary steps that may be performed for dynamically activating or de-activating local media gateways during a multiparty audio and video (AV) conference call, in accordance with an embodiment of the invention. Referring to FIG. 4, the MGs 110 a-140 h are organized into a tree-like structure within the media gateway hierarchy 100 according to selected resource management metrics such as minimizing end-to-end total latency. The exemplary steps may begin with step 402, in which it may be determined whether client devices become active to join in a call during multiparty AV conferencing. In instances where the client devices 150 ₁ and 150 ₆ become active to participate in the call, then in step 404, where the MGs such as the MGs 140 a, 130 a, 120 a, 130 b, and 140 c selected for the call may be activated to support the MGC processing for the call. In step 406, each of the selected MGs 140 a, 130 a, 120 a, 130 b, and 140 c may be operable to set up or establish distributed (point-to-point) connection sessions between the activated MGs to support the call. In step 408, it may be determined whether the client devices 150 ₁ and 150 ₆ are still active for the call. In instances where the client devices 150 ₁ and 150 ₆ become inactive for the call, then in step 410, where the MGs 140 a, 130 a, 120 a, 130 b, and 140 c may be de-activated from the MGC processing and may subsequently release corresponding connection sessions established for the call. The exemplary steps may return to the step 402.

In step 402, in instances where no client devices become active for the call during the multiparty AV conferencing, the exemplary steps stay in the step 402. In step 408, in instances where the client devices 150 ₁ and 150 ₆ are still active in the call, then in step 412, where in instances where more client devices need to become active for the call, the exemplary steps may proceed in step 404. Otherwise, the exemplary steps may proceed in step 406.

For example, the MG 149 a may be operable to aggregate the gateway resources from the MG 130 a and the MG 140 b to provide gateway processing for the multiparty conferencing. For the selected resource management metrics, the look-up table 222 may be utilized to indicate or determine the aggregated resources required at the MG 149 a. The aggregated gateway resources may be shared among the plurality of MGs 110 a-140 h. In an exemplary embodiment of the invention, each of the plurality of MGs 110 a-140 h may be activated to operate as media gateway controller (MGC). In this regard, the MGC processing such as call routing and resource management may be performed at each of the plurality of MGs 110 a-140 h utilizing the shared aggregated gateway resources.

The MGC processing may enable running the multiparty conferencing among the plurality of client devices 150 ₁-150 ₁₆. In instances where one or more client devices such as the client devices 150 ₁-150 ₂ may become idle, the serving MG 140 a mat be de-activated from the MGC processing for the multiparty conferencing. The established connection sessions between the idle client devices and the serving MG 140 a may be released upon de-activation of the MGC at the MG 140 a. In an exemplary embodiment of the invention, gateway resources may be managed at each of the plurality of MGs 110 a-140 h based on the selected resource management metrics. Distributed connection sessions may be established at each of the plurality of MGs 110 a-140 h based on the corresponding gateway resource management.
